The Guano de Paris Pigeon House Also Collects Bird Poop for Compost

Designer Jean-Sébastien Poncet imagined a multi-use terracotta apartment complex for sheltering urban pigeons and turning their poo into compost. Intended for the French capital, “The Guano de Paris” aims to rehabilitate the birds, collect their droppings and facilitate a peaceful coexistence with citizens.

Produced in partnership with the Sheet Metal Forézienne, the terracota and steel design collects the birds’ droppings and mixes them with a vermicompost to produce what’s essentially pigeon poo fertilizer. The resulting fertilizer can be used for the green spaces or sold back to citizens, in turn creating a more friendly, social relation between the birds and humans.

Moreover, the designers see these compartments being placed in parks, providing the city with a safe way to manually sterilize eggs and promote a healthier fixed bird population.
